When San Francisco Police Department Detective Rebecca Madsen (series star SARAH JONES) is assigned to a grisly homicide case, a fingerprint leads her to a shocking suspect: Jack Sylvane (guest star JEFFREY PIERCE), an Alcatraz inmate who died over 30 years ago. Given her family history -- both her grandfather and surrogate uncle, Ray Archer (series star ROBERT FORSTER), were guards at the prison -- Madsen's interest is immediately piqued, and once the enigmatic, knows-everything-but-tells-nothing government agent Emerson Hauser (series star SAM NEILL) tries to impede her investigation, she's doggedly committed.
Madsen will see everything she thought she knew about her family's past shattered, all while fighting to keep the country safe from history's most dangerous criminals.
